In a random sample of sixsix microwave ovens, the mean repair cost was $65.0065.00

and the standard deviation was $11.0011.00. Assume the population is normally distributed and use a t-distribution to construct a 9090% confidence interval for the population mean mu. What is the margin of error of mu Interpret the results.The 9090% confidence interval for the population mean is

(nothing ,nothing ).(Round to two decimal places as needed.)The margin of error is nothing .

(Round to two decimal places as needed.)

Interpret the results. Choose the correct answer below.

A.

It can be said that

9090%

of microwaves have a repair cost between the bounds of the confidence interval.

B.

With

9090%

confidence, it can be said that the population mean repair cost is between the bounds of the confidence interval.

C.

If a large sample of microwaves are taken approximately

9090%

of them will have repair costs between the bounds of the confidence interval.

D.

With

9090%

confidence, it can be said that the repair cost is between the bounds of the confidence interval.
